15x^2-78x+93.5=0
a = 15; b = -78; c = +93.5;
Δ = b2-4ac
Δ = -782-4·15·93.5
Δ = 474
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-78)-\sqrt{474}}{2*15}=\frac{78-\sqrt{474}}{30} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-78)+\sqrt{474}}{2*15}=\frac{78+\sqrt{474}}{30} $
